Although the 2014 referendum was described as a once in a generation vote, Sturgeon said the situation had changed with the result of last year's EU membership referendum in that the people of Scotland backed staying in the EU.

Sturgeon said: "My argument is simply this: when the nature of the change that is made inevitable by Brexit becomes clear, that change should not be imposed upon us. We should have the right to decide the nature of that change."

"The people of Scotland should have the right to choose between Brexit -- possibly a very hard Brexit -- or becoming an independent country, able to chart our own course and create a true partnership of equals across these islands," she also said. "I hope the British government will respect the will of this parliament."

Sturgeon is likely to make the formal request to the British government for a section 30 later this week, after May formally starts the Brexit process on Wednesday by triggering Article 50.
